Frontier Airlines charges for checked baggage, with fees that vary based on when you add the bags and your travel destination. Checked baggage fees generally start around $30 if you add it during booking and increase as you get closer to your departure. Checking a bag at the airport may cost you more, often ranging between $40 and $55.
The maximum weight for checked bags is 40 pounds (18 kg), and if your bag exceeds that, additional fees will apply. To avoid extra charges, weigh your bags ahead of time and plan accordingly.
